' LAND-ROLLER.

Patented J an. 23, 1906.

Application filed March 28, 1905. Serial No. 252,555.

To all whom it may concern.-

Be it known that I, JOHN H. WOLF, a citizen of the United States, residing at Cottagegrove, in the county of Dane and State of Wisconsin, have invented certain new and useful Improvements in Land-Rollers, of.

adjustmg the rollers to actuate the same under variation in conditions of service.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings, in which Figure 1 is a plan .view of an implement embodymg the invention. Fig. 2 is a transverse sectional view. Fig. 3 1s a longitudinal vertical sectional view. Fig. 4 is a perspective view" of the frame, the rollers and the supporting members being omitted. Fig. 5

is a detail perspective view of a roller and a supporting member therefor.

Corresponding and like parts are referred to in the followin descriptlon and indicated in all the views 0 the drawings by the same reference characters.

Describing specificall the construction of the implement, a suitab eframe 1 of approximately rectangular form is used, a tongue 2 being projected from the front of the frame for attachment of the draft-animals, said tongue being suitably braced. A seat 3 is carried by the rear transverse bar of the frame 1, and the driver of the implement is seated thereon when the same is m use. A transverse intle-rod 4 is arranged longitudinally of t e front bar of the frame 1 and is carried in suitable brackets 5, attached to the front extremities of the side bars of said frame. A pluralit of rollers 6 and 7 operate between the sides of the frame 1, and said rollers are mounted in supporting members 8, pivoted at the front ends thereof to the pint e-rod 4. The supporting members of the rollers 6 and 7 comprise spaced bars 9, the opposite ends of the bars of each supporting member being curved outwardly from each other, as shown at 10. Blocks 11 are disposed at oints between the ends of the bars 9 of eac member 8, and transverse fastenings 12 pass through these blocks to the bars 9, securing the same together. The front extremities of the bars 9 are provided with apertures through which the pintle-rod 4 passes, and the rear extremities of the said bars are likewise provided with apertures forming bearings for short shafts 13, u on which rollers 6 and 7 are mounted. he rollers 6 are located nearer the front of the implement than the rollers 7, and said rollers 7 are substantially as wide as the space between the several rollers 6 in order that as the implement advances the ground will be thoroughly reduced, since the said'rollers pass over every portion of the land. The rollers 7 are quite a little wider than the rollers 6, as shown most clearly in the draw- Ihe supportin -bars 8 of the rollers 7 are of course somew at lon er than the similar members carrying the r0 lers 6, said rollers 6 operating in the space between adjacent s ace-bars of the supporting members 8 of t e rear rollers-7.

The rollers above described are yieldably supported in the frame 1 of the implement, and for this purpose adjusting-levers 14 are located at opposite sides of the frame, being arranged longitudinally to the side bars thereof. The adjustinglevers 14 are pivoted at their front ends to the end portions of the pintle-rod 4. The rear extremities of the said levers 14 are projected laterally to form handles 15 to facilitate ready manipulation of these levers under workin conditions. Standards 16 project upwardly from the rear end portions of the sides of the frame 1, and these standards are provided with a plurality of verticall -arranged openings 1 7. Alug 15, extending aterally from the rear end portion of each adjusting-lever 14, is adapted to be received in a selected one of the openings 17 to hold the adjusting-lever at a predetermined adjustment with relation to the frame. Between the front and rear ends of the adjusting-levers 14 are located two outwardly and upwardly curved members 19, having the upper portions thereof threaded to receive nuts 20. Transverse bars 21 extend across the frame 1 above the supporting members 8, 1

and these bars are provided at the ends thereof with openings through which the threaded members 19 pass. The bars 21 are not only connected with the adj usting-levers 14, but bolts 24 pass through these bars to the side bars of the frame 1, forming guide members to direct'the movement of the bars 21 vertically. Springs 23 are interposed between the blocks 11 of the supporting members 8 and the bars 21, said bars 21 being arranged above the transversely mounted blocks of the supporting members 8 of the rollers 6 and 7. It will thus be noted that the rollers 6 and 7 are yieldably mounted in the frame 1 and are adapted for flexible movement vertically in said frame. Further, the rollers 6 and 7 are individually mounted and are adapted to yield when the implement passes over inequalities in the ground, or said rollers will move into depressions under the spring-pressure of the parts 23. The bolts 22 pass through the blocks 11 and the bars 21, and the springs 23 are coilsprings through which the bolts pass in order to revent displacement of the springs. It wil be understood that the tension of the springs 23 may be increased or decreased by lowering or raising the adjusting-levers 14, and this may be done very quickly in a manner which will be readily apparent. Further, the springs 23 may also be adjusted permanently by moving the nuts 20 in the desired direction, the adjustment of the tension of the springs in the Words above set forth being very advantageous in adapting the implement for use in reducing soils of different character.

Having thus described the invention, what is claimed as new is 1. In an implement of the class described, the combination of a frame, su porting members pivoted at the front ends t ereof to the frame, rollers carried by the rear ends of the supporting-bars aforesaid, bars arranged across the frame, springs between said bars and the supporting members of the rollers, and levers pivoted at their front ends to the frame and having adjustable connection with the bars aforesaid.

2. In an implement of the class described,

the combination of a frame, supporting members pivoted at the front ends thereof to the frame, rollers carried by the rear ends of the supporting-bars aforesaid, bars arranged across the frame, springs between said bars and the supporting members of the rollers, levers pivoted at their front ends to the frame and having adjustable connection at their rear ends with the frame, and connecting means between the levers and the bars aforesaid.

3. In an implement of the class described, the combination of a frame, a pintle-bar mounted in the frame, supporting members pivoted at their front ends to the pintle-bar, rollers at the rear ends of the supporting members, adjusting-levers pivoted to the pintle-bars and arranged at opposite sides of the frame, connecting means between said adj usting-levers and the supporting members of the rollers, and means for adjusting the adjustin -levers.

4. I n an implement of theclass described, the combination of a mounted in the front portion of the frame, supporting memberspivoted at their front ends to the pintle-bar and comprising spaced bars, blocks connecting the bars of each supportin member at a point between the ends thereo rollers j ournaled between the spaced bars of each supporting member at the rear portions of the latter, adjusting-levers pivoted at their front ends to the pintle-bars and having adjustable connection at their rear ends with the frame, transverse bars extended across the frame and adjustably connected at the ends of the adjusting-levers aforesaid, and springs interposed between the transverse bars and the blocks of the-supporting members of the rollers.

In testimony whereof I afIlX my signature in presence of two witnesses.
